When posting non-standard scripts, you should indicate which shell they are for.
Even better is to use standard syntax:

The first one without "tee" works fine. echo "$INPUT" displays the values I type in for input. The second one always shows $INPUT as empty string. Why?[/code]
Where have you output the value of $INPUT? Not in $COMMAND, which is what you are redirecting.
Quote:
[code] Is there any other way to execute a shell function and capture its log output and at the same time display its output on the stdout device too without impacting its actual behavior? As you can see here, although the fucntion exports the variable INPUT, it is not available when the function call returns to the calling script code.
export does nothing there; export makes variables visible to child processes, not parent processes.
You are executing $COMMAND in a pipeline, and all elements of a pipeline (all but the last in ksh) are executed in a subshell.

service(8) System Manager's Manual service(8)NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
